The pizza stone from Pampered Chef that we received as a gift cracked upon first usage.  Pampered Chef sent us a replacement for free, but specified in their note to us that if this replacement stone cracked, there would be no free replacement.  That seemed odd.  Unfortunately, the replacement stone cracked last night, again upon first usage.  We followed all of the directions for its care, too.  The pizza came out great, but the stone was cracked from handle to handle, just like the first one.
